我正试图将模型.py拆分为一个文件夹中的多个文件。
做那件事的正确方法是什么？
8年前互联网上的所有方法，现在都不起作用了。
更新1:
test1
__init__.py
admin.py
apps.py
tests.py
views.py
migrations
models
__init__.py
comment.py
like.py
post.py
profile.py
内部init.py
from django.db import models
from django.conf import settings
from .like import Like
from .post import Post
from .profile import Profile
from .comment import Comment
内部comment.py
class Comment(models.Model):
commented_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
for_post = models.ForeignKey(Post, on_delete=models.CASCADE)
内部like.py
class Like(models.Model):
liked_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
post = models.ForeignKey(Post, on_delete=models.CASCADE)
内部post.py
class Post(models.Model):
posted_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
内部配置文件.py
class Profile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
当我尝试进行迁移时：
python manage.py makemigrations test1
我得到了这个错误：
(sandbox-qFsmxchL) λ python manage.py makemigrations test1
Traceback (most recent call last):

class Like(models.Model):
NameError: name 'models' is not defined
您可以将它们放入模型文件夹中，例如：
models/
- __init__.py
- model_1.py
- model_2.py
并且CCD_ 1应该导入包含在其他文件中的所有模型
from .model_1 import Model1
from .model_2 import Model2
这取决于你是否有很多模型，以及这些模型是否彼此有密切的关系。
编辑：
内部init.py
from .post import Post
from .like import Like
from .profile import Profile
from .comment import Comment
内部comment.py
from django.db import models
from django.conf import settings
from test1.models import Post
class Comment(models.Model):
commented_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
for_post = models.ForeignKey(Post, on_delete=models.CASCADE)
内部like.py
from django.db import models
from django.conf import settings
from test1.models import Post
class Like(models.Model):
liked_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
post = models.ForeignKey(Post, on_delete=models.CASCADE)
内部post.py
from django.db import models
from django.conf import settings
class Post(models.Model):
posted_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
内部配置文件.py
from django.db import models

class Profile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
